The best click tracker?

I’ve been testing a few recently and curious what people here are actually using.

- ClickFlare – setup was surprisingly quick and the reporting dashboard is clean. The tracking templates made connecting traffic sources pretty easy.

- RedTrack – powerful but the interface felt a bit complicated at first.

- Voluum – solid but pretty expensive.

- ClickMagick – easy to start with but feels a bit limited.

Curious what others here are running once they start scaling traffic.
